amount for each piece operation. When a number of shoes of a certaintype are to be made up, it is the practice to make out a number of ordercards. thereon in duplicate columns the identifying numbers of the pieceoperations that are necessary to make up the particular type of shoe,together with other data. The various-workmen cut out of the card, withspecial punches that are provided for the purpose, coupons taken fromone of the columns which bear thepiece number of the operation that theyperform and the job number of the order. When the work is completed theyturn in the couponsand are paid at a rate which has been previously setfor the par- It is an object of the present invention to provide astencil printing machine arranged to print up the order cards abovedescribed.

In afactory that is equipped to manufacture a large amount of difierenttypes of shoes there may be a large number, say three or four hundred,different piece operations required to make up all of the types ofshoes. Each stencil of the stencil collection associated with thestencil printing machine has data thereon for one particular pieceoperation. When one particular type of shoe is to be made, it isobviously undesirable to print up order cards with all the pieceoperations for all of the types of shoes thereon. Consequently, it is afurther object of the present invention to provide a stencil printingmachine for the purpose herein set forth with selector mechanism soarranged that,

Each card has listed while all of the stencils of the collection are runthrough the machine when the order cards are being printed, only thosestencils which relate to the particular type of shoe to be made arecaused to be operated upon by the printin machine.

A further 0 ject of the invention is the provision of a stencil printingmachine and a stencil collection therefor with the machine so arrangedthat the stencils are returned to the collection automatically afterthey have been run through the printing position of p the machine.

Another object of the invention is the provision of a stencil printingmachine and a collection of stencils which are arranged in apredetermined order, combined with a selector mechanism which isarranged to condition the machine to print from certain stencils in theorder in which they occur in the collection.

The order or work coupon card is provided with punch holes adjacent thepiece numbers in both columns of the card so that the operative canlocate his punch to punch out a coupon in one column that registers withother printed data, as the job number, adjacent each piece number in thecoupon column of the card. I

A yet further object of the invention is to provide a stencil printingmachine wherein the card punching and job number printing are carriedout on the card in operations which follow the stencil printingoperation.

The machine embodying the present invention comprises atable 20 belowwhich is located the power mechanism22 which is of a type well known inthe art unnecessary to describe further that serves to reciprocate theoperating rod 24 under control of a treadle 26 by means of which themechanism can be started and stopped. Power is supplied to thepowermechanism by means of a shaft 28 fromwhich power is also taken. tooperate the inking mechanism and the stencil elevatin and returninmechanism hereinafter to be described. pair of spaced stencil tracks 30are disposed above thetable and aesaeas extend lengthwise thereof andare adapted to guide successive stencils into and out of printingposition. The collection of stencils A is contained in a stencil holder32 which is located mainly above and at the right hand end of thestencil track and in line therewith (Fig. 1). A stencil pusher 34 of awell known type not necessary to describe and illustrated in greaterdetail is disposed beneath the pile of stencils in the holder 32 and isarranged to be reciprocated under said pile to move the lowermoststencils successively out of the pile and into and along the stenciltrack.

A printing platen 36 is located beneath the stencil track and issupported by arms 38,

see Fig. 3, which are pivoted to depending brackets 40 of the stenciltable. A printing roll 42 is located above the stencil track and theplaten and is journalled between rearwardly extended arms 44 which areconnected to a horizontal yoke 46 pivoted on a horizontal shaft 48carried by said arms 40. Inking mechanism 50 of a well known type islocated above the printing roll 42 and is adapted to supply ink thereto.Components of said inking mechanism are rotated from the driving shaft28 by means of belts 52 and 54 and the interposed countershaft 56, seeFig. 1. The paper strip 6 from which the coupon card is made is passedthrough an opening 58 in said yoke and under the stencil tracks 30 andabove the platen 36.

The inklng roll and platen are adapted to be moved toward each other tosupport the strip in printing position and to press a stem cil a againstthe strip. To this end, an arm 60 is pivoted on a shaft 62 carried bythe depending brackets 40. Said arm 60 has an upstanding integral arm 64which terminates in an upper cam face 66 that underlies a roller 68carried by the platen arms 38 and is so arranged that when said arm 64is rotated in a counterclockwise direction, it raises the platen andholds it in an elevated position until the arm is restored to aninoperative position, as shown in Fig. 3.

The yoke 46 is integral with a depending arm 70 that is connected to thearm 60 through links 72, whereby both the platen and the printing rollare operated conj ointly. The stencil pusher is operated conjointly withthe laten and printing roll and all are operated y ,an arm 74, see Figs.3 and 5.

Said arm 74 is journalled on the shaft 62 and is pivotally connectedwith the upper end of the reciprocating actuating rod 24 so that saidarm is reciprocated by said rod. The

76, Fig. 1, which is pivotally connected at one end with the stencilpusher 34 and at the other end with a forwardly extended arm 78 of astencil pusher is operated by means of a link i said arm 74. Thearrangement is such that as said arm 74 is reciprocated vertically, thehub 78 is caused to be reciprocated about its vertical axis thereaboutto reciprocate the stencil pusher.

Said arm 74 has a locking and releasing connection with the printingroll and platen so that it can operate the printing roll and platen whena selected stencil passes into printing position and, can alsoreciprocate without operating the printing roll and platen.

To this end the arm-6001': the printing mechanism, see Figs. 3, 4 and 5,is extended alongside the outer end ofsaid arm 7 4 and carries at itsouter end a pivotally mounted latch member 86. Said member has a toothor projection 88 which is adapted to enter a notch 90 in the outer faceofsaid arm 74 under action of the tension spring 92 whereby to lock saidarms 60 and 74 for conjoint reciprocatory movement. When the latch 76,however, is held out of engagement with said arm 74, as illustrated inFig. 5, the

arm 74 can reciprocate, without operating the arm 60, which remainsmotionless.

Selector mechanism is provided to control the latch member 86 and itsconnection with 'the arm 74. The selector mechanism includes avertically disposed latch-release arm 94 which is j ournalled in adepending bracket 96 carried by the rear edge of the table 20. Said arm94 has a depending extension '98 that is disposed infront of aroller-100 carried by an upper end of the latch member 86 and is adaptedto engage said roller on movement in a counterclockwise direction andeffect the disengagement of said latch member 86 from said arm 74. Therelease arm 94 is disposed normally in position to maintain said latchmember 86 disengaged from the arm 74 and is locked releasably in suchposition by a latch 102 which is loosely carried on a shaft 104. Saidlatch 102 normally engages a lower detent106 of said release arm 94whereby to hold it in position as illustrated in Fig. 5. When the latch102 is raised, it is caused to release the detent whereupon the releasearm 94 can move in. a clockwise direction under action of a tensilespring 108 to permit the latch member 86 to engage the arm 4. v v Thelatch 102 is operated by means including an clectromagnet 110 Fig. 4which is adapted to be energized by further elements I of the selectormechanism hereinafter to be described. The armature 112 is pivotedto thebracket 96 and is disposed above said electro-x'nagnet and has anextensionwhich un-, derlies said latch 102. Consequently when saidelectrov-magnet isenergized the armature is drawn down and the extensionis elevated. whereby to elevate the latch and disengage it from thedetent 106 so that the release arm 104 is free to operate and causeconnection to be made for the operation of the printing roll and platen.

The selector mechanism includes a metal disc 114, see Figs. 3, 4 and 6,which is located above the table 20 at the rear of the stencil tracksand is j ournalled on a shouldered screw 116 carried by the supportingbracket 118. A selector disc 120 composed of paper or other electricallyinsulating material and best shown in Figs. 2 and 6 is located on oneface of said disc and is provided with a plurality of perforations 122therein near the outer edge thereof through which a contact member ofthe selector mechanism may be moved into engagement with the discs 114whereby to complete the electrical circuit for the electro-magnet 110.'The insulating disc 120 is clamped removably to the face of said disc114 by a clamping drum 124 which is re- :movably secured to a screwthreaded stud 126 that is secured to the hub of the disc 114 coaxialwith the screw 116.

The disc 114 together with the insulating selector disc 120 is adaptedto be rotated in a.

bracket 118 and carries a roller '138 at its lower end which rides uponthe cam face of a horizontal segmental cam member 140. Said cam memberis located beneath the table 20 and is journalled on a vertical stud 142therei of and has a rearwardly directed extension 144, see especiallyFig. 2, which is pivoted to a link 146. The other end of said link is.

pivoted to the pusher operating arm 78. Thus at each operation of thepusher, the cam is reciprocated and the disc 114 is caused to 'beadvanced step bystep whereby to bring the perforations 122 of theinsulating selector disc 120 successively in front of a contact member148, see Figs. 1, 4, 5, 7 and 8.

Said contact member is carried by a ring 150 which is, detachablyreceived on a post 152. Said post is secured to and is insulated from abar 154 that is slidable horizontally in a bracket 156 carried by thebracket 118. A tensile spring 158 is connected between said bar 154 andthe bracket 156 and biases said contact member for movement toward thecils into and out of' rinting position with printing'therefrom. aidcontact member is reeiprocated by means of a pivoted arm 160 whichengages the free end of the bar 154. Said arm is connected through alink 162 with an arm 164 of the aforesaid shaft 104 so that when saidshaft 104 is moved in a clockwise direction, the arm 160 is caused topush said bar 154 and consequently the contact member away from theselector disc. When the shaft 104 moves in a clockwise direction, thespring 158 causes the opposite movement of said contact member to bringit into engagement with the insulating selector disc 01' to move itthrough an aperture thereof into electrical engagement with the disc114. In the latter case, the circuit through the electro-magnet 110 isadapted to be com pleted whereby to effect the connection between theoperating arm 74 and the printing mechanism, in the manner above setforth.

The shaft 104 is reciprocated by means of a depending arm 166, see Figs.4 and 5, the lower end of which is provided with a cam roller 168 whichis located beside the outer end of the arm 74 and in operative relationwith the cam face 170 of a cam block 172 fixed to one side of said arm74. The shape of said cam face 170 is such that when the arm 74 movesupwardly and is traversing the latter part of its range of movement, thearm 166 is permitted to move in a counterclockwise direction and therebypermit the spring 158 to move said contact member toward the selectordisc. During the downward movement of said arm 74 the.reverse actiontakes place. If the selector disc 120 has one of its perforations 122disposed in front of the contact member, the electro-magnet is energizedand the release arm 94 is released to permit the connection between thelatch member 86 and the arm 7 4. On the next upward stroke of the arm74, the release arm 94 is adapted to be again restored to its normalposition. To this end, the arm 94 is provided with a cam roller 174which is adapted to be engaged by the inclined cam face 176 of a cam 178carried by the arm 74. It is apparent that as said arm 74 is movedupwardly the machine. Thus each forward step of thev disc correspondswith one operation of the machine to pass one stencil into and out ofprinting position. The perforations 122 in the disc are peripherallyspaced from each other by distances which correspond to the eeaeeelocations of the selected stencils in the collection so that the machineoperates only on selected stencils.

The stencils of the collection are adapted to be returned automaticallyinto the top of the stencil holder 32 after they have been passedthrought the printing position whereby to enable the machine to print upduplicate order cards without unnecessary interruption. To this end,means are provided to take the stencils from the delivery end of thestencil track and elevate them approximately to the level of the top ofthe stencils in the holder and return them to the stencil holder. Theelevating means, see especially Figs. 1, 2 and 9, is located at the lefthand side of the machine above and at one end of the stencil track andcomprises essentially two duplicate stencil raising devices the lowerone of which feeds into the upper device. These devices are constructedessentially as illustrated in the Sterling Elliott Patent No. 1,210,440,dated June 2, 1917. The lowermost raising device comprises a pair ofspaced side plates 180 which are arranged in line with the stencil trackand have aligned circular grooves 182 formed in their confronting facesin which the ends of the stencil are adapted to be received. A shaft 184is journalled in said plates and carries a yieldingly supported frame186 which has a pair of outstanding arms 188. The shaft is adapted to berotated whereby to move said arms into engagement with a stencil in thestencil track and to move the stencil upwardly in the circular grooves182 to the upper part of the device.

The uppermost raising device. is similarly provided with a pair of endplates 190 which are supported upon the lower plates 180 and havealigned circular grooves 192 that communicate with the lower grooves182. A shaft 194 is journalled in said plates 190 and carries a yieldingframe 196 which has arms 198 that are revolved as the shaft is rotatedto move the stencil from the upper portion of the lower grooves 182upwardly in the grooves 192 into the upper portion of the plates andonto a conveyor belt 200.

It will be noted that the lowermost stencil elevating device reversesthe position of the stencil while the uppermost is deposited on theconveyor belt in the same position in which it passes through the track.This is a desirable feature in that it keeps the same facesof thestencils always uppermost in the stencil collection. v I

The shafts 184 and 194 of the raising and lowering devices are connectedtogether for conjoint rotation at equal speeds by the shaft 202 and thesets of meshing bevel gears 204. The two shafts are driven by means of asprocket wheel 206 which is fixed to the lower shaft 184 and is drivenfrom a sprocket 208 fixed tothe drive shaft 28 by a chain 210.

The conveyor belt 200 is endless and is driven by a pulley 212 fixed toa shaft 214 which is j ournalled to brackets 216 carried by one of theend plates 190 of the upper elevatin mechanism. The shaft 214 is drivenby a elt 216 from the power shaft 28. The upper and lower passes of theconveyor belt 200 are practically superimposed at the upper elevatingdevice and the lower pass of the belt is supported on an idler roll 218journalled between said brackets 216. The passes of said belt areextended forwardly to the stencil holder 32. The forward end of the beltis passed about a pulley 220 which'is located between the side lates 222of an adjustable belt supporting rame, see Figs. 1 and 10. Said platesextend above the top pass of the belt whereby to prevent the stencilsfrom falling off the belt. I

The height of the right hand end of the belt with respect to the stencilholder is varlable and to this end the side plates 222 of the beltsupporting frame are pivotally mounted on a shaft 224 which is carriedby brackets 226 secured to the right hand plate 190 of the upperelevating device. The r1 ht hand end of the belt supporting frame as apair of forwardly extended ar 228, see especially Fig. 11, which haveslots 230 in their forward ends through which pins 234 are looselyextended. Said p1ns are carried by a generally U-shaped clamping frame236 which surrounds the stencil holder and can be secured in anyvertically ad1usted position thereon by the set screw 238. By raisingand lowering said frame 236 the belt supporting frame can also beraisedand lowered whereby to'bring the top pass of the beltapproximately at a suitable height with respect to the top of thestencil collection in the holder. The frame 236 is provided with avertical plate 240 which is located at the left side of thestencilholder beneath and forwardly of the conveyor belt and in a position toengage the ends of the stencils 1n the upper part of the holder and toreta n them in position in the holder in any posltion 1n which the beltsupporting frame may be adjusted. With this arrangement, the machine isadjustable to receive and operate upon stencil collections of variousslzes.

The order card which is the product of the present machine and fromwhich the piece work coupons are cut is illustrated in Fig. 17. The cardI) is printed from a relatively long and narrow strip of paper and has'two data columns 0 and d. The two columns have rows of duplicate data6, f, g, and the like which indicate the type numbers of particularpiece work operations togctherf with other data 2' which may indicatethe price the workman is paid for each operation or the like. Such datais borne by the different stencils and is adapted to be printed on theorder card by the stencils when they are in printin position beneath theprinting roll and p aten. The right hand column al also bears series ofnumbers h, each series being duplicated in the difierent lines of thecolumn. This data may re resent the order number for the. order of s oesthat is to be manufactured. The order numher is printed on the card bymechanism independent of the stencils. The card also bears in the column0 a row of perforations k and in the column d a row of perforations lwhich are staggered with respect to the perforations 1:. Theseperforations are guide perforations which are adapted to receive prongsof a special punch employed by the iece workmen to cut out of the columnd 0 the card small coupons m, the outline of which is shown in thedotted lines. Each coupon bears the order number k and the piece workoperation data e. At the same time the coupon is cut out, the punchusually prints on the card opposite the space vacated by the coupon theworkmens numbers. The card with the coupons cut out is retained by thefactory mana ement while-the coupons are turned into t e office by theworkmen after the work called for by the piece work operation numbershave been performed; and the workmen are credited with amounts asindicated by the cou ons. The perforations k and Z are formed 1n thecard as a step following the stencil printing operation.

The order number printing and card punching mechanisms are illustratedmore particularly in Figs. 2, 3, and 12 through 16. Said mechanisms arecarried by a. plate 242 which is secured upon the table 20 in front ofthe printing roll. A horizontal shaft 244 is journalled in upstandingbrackets 246 of said plate and has fixed thereto a rearwardly extendedarm 248 which underlies one of the arms 44 which support the printingroll and is adapted to be engaged and depressed by a cam roller 250carried by said arm when the printing roll is depressed, thereby to turnsaid shaft in a clockwise direction. Vertically depending punches 252are pivoted to arms 254 fixed to said shaft 244 and operate in bushings256. Female dies 258 are located beneath said punches. The paper stripor card b is adapted to be moved forwardly above said female dies andbeneath said punches and is held stationary at the time the punchesdescend to form the holes In and l in the strip. Tubes 260 are locatedbeneath the female dies 258 and serve to conduct the punchings into areceptacle 262, see Fig. 1, or into some location away from theoperative parts of the machine.

The printing device 264 for the order numbers h of the card is locatedin front of the punches and above the card strip. Said printing deviceis of the self-inking type which is common in the art and need not befurther described except to state that it includes a vertically movableframe 266 which bears the printing characters and is movable downwardlyto print upon the paper strip and is restored to elevated position by Ia compression sprin .268 which encircles the vertically movab e rod 270that carries the printing frame. Said rod 270 is dem pressed to effectthe printing operation by means of a roller 272 which bears upon the topof said rod and is carried between arms 274 of a frame that isjournalled on a shaft 276 carried by the upstanding arm 278 of a bracket280 supported by the plate 242. Said arms 274 are reciprocated bymechanism operated by includes an arm 282 which is fixed to said shaft244. A yoke 284 is pivoted on a screw 286 carried by the upper end ofsaid arm. Said yoke has a forwardly extended tube 288 in which isslidably received a rod 290, which rod is carried by a yoke 292 pivotedon an arm 294 fixed to the shaft 276. A compression spring 298 encirclessaid tube and rod and bears against both yokes. Pins 300 and 302 arefixed in said tube and rod respectively and engage the convolutions ofsaid spring so that as said yoke 284 is moved to the right, Fi s. 12 and13, by the clockwise movement 0 said arm 282, the motion is transmittedthrough said spring to the arms 274 and consequently the plunger or rod270 of the printing device is depressed into printing engagement withthe paper strip. When said arm 282 is moved in the opposite direction,the plunger of the printing device is released and is raised by a spring268 into a position free from the paper strip.

The arm 282 is held yieldingly in a normal or inoperative position bymeans of a tensile spring 304, one end of which is connected with an arm306 integral with said arm 282 and the other end of which is connectedwith a fixed support.

The paper strip is fed forwardly in a step by step manner by a pair offeed rolls 307 which are located above the paper strip 6 immediately inthe rear of'the stencil track and are fixed to a horizontal drive shaft308. Said shaft has a gear 310 thereon which meshes with a gear 312fixed to a shaft 314 that is located above the feed roll shaft and isjournalled in a suitable bracket 316. An arm 318 is loosely mounted onsaid shaft 314 and is pivotally connected with an upwardly and forwardlyextended link 320 which has a longitudinally elongated slot at its upperend. An arm 324 is fixed to and upstands above the arm 306 and has atits upper end a screw 326 that is loosely received in the slot 322. Aspring urged pawl 328 is journalled on the pivotal connection 330between the link 320 and the arm 318 and engages a ratchet 332 fixed tothe shaft 314 the shaft 244. Said m ebliamsm so that as said arm 318 isreciprocated a step by step movement in' one direction is imparted tothe shaft 314 and consequently to the the printin clockwise directionwithout driving the feed rolls. When, however, the printing roll iselevatedthe spring 304 operates to move the.

arm 318 through the link 320 and the arm 324 and thus rotate theprinting roll andadvance the paper sheet forwardly by a suitable amount.

A brake drum 334 is fixed to the ratchet shaft 314, see Figs. 14 and 15,and is engaged by a friction shoe 336 to hold the ratchet andconsequently the feed rolls from undesired rotation.

When the strip is first passed through the machine, the piece work datae is printed by the stencil. In the next operation the strip is movedbeneath the punch and, in the following operation, beneath the job orderprinting device. The punch and the job order printing device operatetogether so that the job number is printed on the first-line while theholes are punched on the second line and the third line is being printedby the stencil. At the end of the collection of stencils, holes remainto be punched in the last two lines and the job order numberto beprinted on the last' three lines. Consequently means are provided tooperate the card feeding and job printing devices by hand whereby toeffect the necessary operations on the last three lines on the card.This is conveniently done by a handle 338 which is fixed to and extendsforwardly of the arm 282. By the manipulation of the handle the shaft244 is operable independently of the operation of the printing mechanismthus to operate the card feeding mechanism and the punching and jobprinting devices.

When the card is to be removed from the machine, the feed rolls can bedisabled. The card is pressed against the feed rolls 306 by press rolls340, which are located beneath the feed rolls and are carried by arms342 of ajframe pivoted to brackets 344 which depend from the table 20.Said frame is provided with a forwardly extended arm 346 that is urgeddownwardly by .a compression spring 348 thus to maintain the rolls 340against the card in contact with the feed rolls 306; Said rolls 340 canbe held in a low position free from operative association with the feedrolls by means of a pivoted hand lever 350 which has an inclined camslot 352 therein in which a pin 354 of said arm 346 is loosely received.By moving said lever 350 in a counterclockwise direction, the arm 346 iscaused to be raised and held in raised position until the lever 350 isrestored to the position illustrated in 3.
